Hashtags and retweets : using Twitter to aid Community , Communication and Casual ( informal ) learning

Since the evolution of Web 2.0, or the Social Web, the way in which users interact with/on the Internet has seen a massive paradigm shift. Web 2.0 tools and technologies have completely changed the dynamics of the Internet, enabling users to create content; be it text, photographs or video; and furthermore share and collaborate across massive geographic boundaries. As part of this revolution, arguably the most significant tools have been those employing social media. This research project set out to investigate student’s attitudes, perceptions and activity toward the use of Twitter in supporting learning and teaching. In so doing, this paper touches on a number of current debates in higher education, such as the role (and perceived rise) of informal learning; and debates around Digital Natives/ Immigrants vs. Digital Residents/Visitors. In presenting early research findings, the author considers the 3Cs of Twitter (T3c): Community, Communication and Casual (informal) learning. Data suggests that students cannot be classed as Digital Natives purely on age and suggests a rethinking of categorisations is necessary. Furthermore, the data suggests students are developing their own personal learning environments (PLEs) based on user choice. Those students who voluntarily engaged with Twitter during this study positively evaluated the tool for use within learning and teaching.


Introduction
Since the evolution of Web 2.0, or the Social Web, the way in which users interact with/on the Internet has seen a massive paradigm shift.Most notably, the Internet was originally a ''tool'' with which users can receive information (Web 1), whereas later, users create that information, share and interact with others (Web 2.0).
Web 2.0 tools and technologies have completely changed the dynamics of the Internet, enabling users to create content; be it text, photographs or video; and furthermore share and collaborate across massive geographic boundaries.As part of this revolution, arguably the most significant tools have been those employing social media.As such, social networking sites (SNSs) such as Facebook have seen tremendous growth in recent years (Kassens-Noor 2012), culminating in its IPO of roughly $100bn, where it is suggested more than 80 million shares were sold in the first 30 seconds (Pepitone 2012).
Although it is quickly growing, microblogging site Twitter is not quite at the same scale yet.Although there are a range of blogs and websites discussing and promoting the use of Twitter in education, little published research into how social media is being used to support learning, learners and the student experience exist (Junco, Heiberger, and Loken 2011;Kassens-Noor 2012).However, research demonstrates how students are integrating various tools based on individual choice to form their own personal learning environments (PLEs) (Dabbagh & Kitsantas 2011;Hall 2009).
This research project set out to investigate student's attitudes, perceptions and engagement in the use of Twitter to support learning and teaching.In so doing, this paper explores relevant literature across three specific and related domains: the role of social networking in the development of the web; the classifications of behaviours of users of the Internet; and the use of such digital tools for learning.
Using Twitter as a voluntary communication platform, and based on early research findings, this paper will also suggests the ''3Cs of Twitter'' (TC 3 ) in Education Á Community, Communication and Casual (informal) Learning.

The Internet and social media
Unsurprisingly, statistics show increases in the use of the Internet over time; Roblyer et al. (2010) draw on Pew research (Lenhart et al. 2007) to compare Internet use from 2001 with 2007.In 2001: . 76% of online teens said they would miss the Internet if they could no longer go online. .48% said their use of the Internet improves their relationship with friends. .32% say Internet tools help them make new friends.
The Pew figures (Lenhart et al. 2007) go on to suggest that 93% of teens in 2007 use the Internet, and increasingly ''as a venue for social interaction'', e.g.create/share content, tell stories and interact (p.3i).The Pew figures also highlighted that the use of email was decreasing amongst teens, and Junco et al. (2011) suggest learners are beginning to favour communication through social networking tools rather than via email.
Specifically within the UK context, the Office for National Statistics reported the number of people accessing the Internet daily had more than doubled between 2006 and 2012; around 87% of 16Á24 year olds used SNSs in 2012; and mobile Internet traffic more than doubled between 2010 and 2012 (The Office for National Statistics 2013).A YouGov survey (n01275) highlighted the pervasive nature of social media, and suggested 65% of the UK online population used Facebook within the last month (February 2012), including 95% of 16Á20 year olds, and 74% of 21Á24 year olds.Interestingly though, the report also suggests that Facebook use is decreasing whilst the use of LinkedIn is increasing (YouGov 2012).
Boyd & Ellison define social networks as; web-based services that allow individuals to: (1) construct a public or semi-public profile within a bounded system, (2) articulate a list of other users with whom they share a connection, and (3) view and traverse their list of connections and those made by others within the system.(Boyd & Ellison 2008, p. 211) This definition aligns with the ethos of social constructivism Á the theory of learning suggesting social interaction is critical to the construction of knowledge (Vygotsky 1967) Á and the formation and participation within communities of practice.
Furthermore, Roblyer et al. (2010) identify 60% of students who use SNSs already use the platforms to discuss their education (in general), with over 50% discussing specific work (Roblyer et al. 2010).Junco, Heiberger, and Loken (2011) also identify positive correlations between SNS use and student engagement.
Therefore, it makes sense that researchers and academics should look to harness these tools and technologies to enhance the sense of community, support communication between learners and tutors, and enable a means for casual (informal) learning.

Social media and the digital divide
Before educators implement a range of technologies, it is important to gain an understanding of the unique nature of students, including their current use of technologies.Schofield suggests this consideration of learners, alongside the purpose of teaching and learning activities, is integral before identifying and implementing technologies (Schofield 2006).
In exploring the digital behaviours of students, Roblyer et al. (2010) suggest that learners check SNSs and email with equal regularity, but faculty are more likely to check email rather than SNSs.This could add weight to suggestions that students are more engaged with current technological trends than teaching staff Á or what might initially appear to be older generations.Prensky's (2001) observations led to the categorisation based on their digital behaviour, and suggested users were either Digital Natives or Digital Immigrants; ''Digital Natives'' Á People born later than 1980, who have some innate confidence in using technology and ''all of the other toys and tools of the digital age''.(p.4).''Digital Immigrants'' Á An older generation of users who have to adapt current practices (and in some cases lifestyles) to harness technologies.
Prensky's work has been widely criticised for such harsh categorisations and exaggerations (Selwyn 2009;White & Le Cornu 2011), such as the suggestion that ''our students' brains have physically changed'' (Prensky 2001, p. 1).White and Le Cornu (2011) recognise the compelling nature of Prensky's work, however suggest his metaphors, as criticised as they are, relate not only to a different time (e.g. 2001), but also to a different Web (1.0).White and Le Cornu go on to offer a new continuum-based typology for online engagement, with more consideration of the now commonplace social networking services available.Careful not to pigeonhole users into age or technical categories, White and Le Cornu use the metaphor of ''Digital Residents'' and ''Digital Visitors'' (White & Le Cornu 2011).
Digital Visitors are those users who may use a tool to carry out a desired function.The tool may not be the perfect fit for the job, but are happy to make some progress to the aims.When the job is over, the tool is put away again.Visitors are not interested in building profiles online.Digital Residents on the other hand, see the social web tools as a place, not too dissimilar from a physical building, or a park: places to meet up with friends and interact.The boundaries between the physical and digital worlds are increasingly blurred.
White and Le Cornu go on to identify Digital Visitors through the metaphor of a garden shed, suggesting: . . .Visitors understand the Web as akin to an untidy garden tool shed.They have defined a goal or task and go into the shed to select an appropriate tool which they use to attain their goal.Task over, the tool is returned to the shed.It may not have been perfect for the task, but they are happy to make do so long as some progress is made.(White & Le Cornu 2011) In relation to this study, Prensky would suggest that students should all be familiar with SNSs such as Facebook and Twitter, whereas White and Le Cornu would suggest users may or may not engage with social media to different levels depending on their personal aims and views on the tools in question.Of particular interest here is if any data obtained in this study can support either typology.

Social media and PLEs
Hall (2009) discusses the need to balance formal learning, e.g.structured/timetabled learning opportunities within an institution, with informal learning, e.g.learning outwith the formal structures and technologies provided by the institution.How learners use and traverse these spaces (and indeed concepts) is of interest in this study, and in particular, the social web technologies that support and enable them to do so.The collection of such technologies alongside and in combination with the formal systems of the university, might be considered a ''personal learning environment'' or ''PLE'' (Hall 2009).Furthermore, social media tools such as Twitter and Facebook can significantly impact upon their development (Hall 2009;Dabbagh & Kitsantas 2011;Kassens-Noor 2012).Through adopting such tools, authors suggest learners can address the ''blurring of the boundaries'' between personal, social spaces and formal learning contexts (Hall 2009).Hall builds on notions that PLEs can ''help integrate formal and informal learning'' in HE (Dabbagh & Kitsantas 2011) suggesting they should be integrated in order to enhance learning.However, in this study, there is an emphasis upon learner choice in the development of such environments, which might prove challenging or contradictory in instances where institutions enforce or even restrict participation to particular systems.
In discussing formal learning environments, both sets of authors (Hall and Dabbagh and Kitsantas) use terms such as ''Institutionally sponsored'', ''highly structured'', ''prescribed learning framework'' and ''specified learning tasks''.These will likely include, for example, the structures in place through institutionally owned virtual learning environments (VLEs).This can be compared with the ''learner owned'' and ''learner developed'' PLEs constructed of tools through personal choice and often including Web 2.0 tools.Although traditionally, academics see the two environments separately (Roblyer et al. 2010), Hall identifies evidence suggesting that eLearning as a whole is ''rarely seen as separate or special by learners'' (p.32), and that students already use a mix of tools (both personal and Institutional) depending on choice, access and control.He goes on to suggest the ways students blend and deploy both informal and formal tools ''underpins their assemblage of a meaningful PLE'' (Hall 2009).
This study is largely interested in the use of social media in the development and formation of learner PLEs, as well as learner's attitudes towards their use in learning and teaching.

The use of Twitter in education
Twitter was launched in 2006 as a microblogging service (Boyd & Ellison 2008), enabling users to send tweets of 140 characters.Similar to other SNSs, Twitter enables users to follow the tweets of other users.As the service has developed, additional functionality has enabled users to include a photograph in their tweet, form lists of users, and third-party tools enable longer tweets and simultaneous posts across multiple SNSs.
Literature suggests that those who have experimented using Twitter in teaching and learning agree that it can have a positive impact on student engagement (Kassens-Noor 2012).
Kassens-Noor's ( 2012) study investigates how students apply, create and retain knowledge when using Twitter, with the leading question: ''Does the use of Twitter aid students in learning a particular subject matter?And, if so, in which learning contexts does Twitter offer advantages over more traditional teaching methods?''(p.12).The implementation of Twitter here was structured, requiring students to tweet about a particular topic in order to complete a credit-bearing assessment.
Participants were asked to: tweet daily; raise a cause for concern related to the subject matter as well as suggesting a remedy; and respond to other tweets in relation to the original concern or the remedy.
Although the sample size was low (15 participants), Kassens-Noor ( 2012) reported positively in relation to the use of Twitter as a ''powerful collaboration tool between students'', ''better suited for creating and sharing large amounts of information'' and useful for ''informal, out-of-classroom assignments'' (p.16).
In comparison with a second group of students keeping journals, tweeters raised more topics for concern and discussion, but tweets were less reflective Á perhaps due to less space, e.g.140 characters.
Several other authors (Junco, Heiberger, and Loken 2011;Roblyer et al. 2010) have identified Chickering and Gamson's Seven Principles for Good Practice in Undergraduate Education (Chickering & Gamson 1999) as a foundation for the use of social media in learning and teaching, and as a means to benchmark ''engagement''.The seven principles of good practice in undergraduate education include: (1) Encourages studentÁfaculty contact (2) Encourages cooperation among students (3) Encourages active learning (4) Gives prompt feedback (5) Emphasizes time on task (6) Communicates high expectations (7) Respects diverse talents and ways of learning To this end, the work of Junco, Heiberger, and Loken (2011) is one of the few empirical studies investigating the impact of Twitter on student engagement, with two leading questions: What effect does encouraging the use of Twitter for educationally relevant purposes have on student engagement?What effect does encouraging the use of Twitter for educationally relevant purposes have on grades?(p.121) In implementing the tool, researchers ran training sessions on the use of Twitter (including explanations on how hashtags work, tweeting another user, etc.), and embedded its use through mini assignments that needed to be completed.They then captured data on the amount of tweets sent and by how many students.The authors suggest; ''Twitter helped students feel more comfortable asking questions they may not be comfortable with asking in class'' (Junco, Heiberger, and Loken 2011, p. 127), and furthermore highlighted a positive effect on both student engagement and grades.They then go on to relate their positive experiences with Chickering and Gamson's principles for good practice, suggesting that their research demonstrated: . Improved contact with faculty (Principle 1) .Improved communication between students (Principle 2) .Promoted active learning (Principle 3) .Prompt feedback (Principle 4) .Maximise time on task (Principle 5) .Communicate high expectations (Principle 6) .Respect for diversity (Principle 7) Finally, in preparation for a keynote presentation, Steve Wheeler asked students at the University of Plymouth for quotes regarding their thoughts on the use of Twitter.He received a number of replies from students, such as: . ''Twitter, we're better connected'' .''Twitter opens the classroom to the world, but also with this, the world of criticism and debate'' .''Twitter has opened a wealth of opportunities and information I never even knew existed.To be honest, might have to blog now''

Literature review summary
The literature identified thus far suggests that today's students are increasingly relying on the Internet as a means for ''Communication'', and largely related to building and maintaining relationships Á ''Community''.It recognises existing attempts to classify users of the Internet, and reports overwhelmingly positive feedback in relation to the use of Twitter in teaching and learning Á informal or ''Casual'' learning.
Limited, but positive feedback from the literature calls for further investigation into the use of Twitter in education, and in particular to explore aspects related to development and participation within a community, as well as communication with, and amongst, groups of students for personal and learning purposes.
This study adds to the small, but growing body of research in relation to the use of Twitter in education.It hopes to add further clarification to the debate around classifying users of the Internet and investigate students' attitudes and practices in relation to Internet access, and in particular, the use of SNSs within the formation of learner-generated, and learner-owned PLEs.use Twitter as a potential solution to help encourage communication between students; provide a backchannel throughout teaching activities; and aid the communication channels between students and teaching staff.

Methodology
Students were informed early on that they did not have to sign up to the service, but support was provided for those students wanting to.These students were encouraged to include dedicated hashtags if they wanted to tweet anything related to the course of study.
Twitter was used by the lecturers in five different modules, across two academic periods/years, with hashtags corresponding to the module codes (actual hashtags have been renamed here to preserve anonymity): Throughout the duration of the modules, the lecturers would regularly tweet links that might be useful to students as well as being available to answer questions, etc.Through the use of hashtags, these tweets could be captured using the Twitter Developer API, which were then embedded within the corresponding area for the unit in the university's VLE.
Due to collaborative delivery arrangements at the university, a number of teaching staff share the workload of each module, with the consequence that Twitter may have been introduced to different modules at different times of the year.For example, Twitter was introduced to #0001 students in Week 1 (September 2011), but was not introduced to #0002 students until Term 2 (January 2012).Similarly, although Twitter was introduced to #0003 and #0004 within the first few weeks of the 12/13 academic period, it was not used much until Term 2 (January 2013).
A short questionnaire built using the university's subscription to an online survey tool was sent to students via a link in a VLE announcement/email.Students were aware that completion of the questionnaire was voluntary and that their participation was anonymous.

Questionnaire
The questionnaire contained 17 questions across two sections, aiming to: (1) gain a picture of the demographics and digital profile of the student group; and (2) identify existing Internet practices and gauge the attitudes toward the use of social media in learning and teaching.The questionnaire contained yes/no, multiple choice and multiple answer questions, with scope for free text comments in response to respondent's perceived benefit of Twitter (Q14).A copy of the complete questionnaire can be found in Appendix 1.
After completion from the 0002 and 0003 groups, two further questions were added to the survey.Firstly, the option of ''Gaming'' was added to question 7 (relating to online activity), and secondly, an add-on question to Q9 about the use of Facebook was added, asking if respondents have discussed university work on Facebook.

Research in Learning Technology
Citation: Research in Learning Technology 2013; 21: 19692 -http://dx.doi.org/10.3402/rlt.v21i0.19692 Introductory questions identified age group and gender, with the potential to crosscheck results to determine patterns.Wherever relevant, this data is provided in the following section.
The questionnaire was sent to all 208 students studying the modules detailed above.The 42 responses represent a 20% response rate.
Ethical approval for this research was granted through the Faculty of Science and Engineering ethics review board.Furthermore, completion of the survey was entirely voluntary and anonymous, adhering to the British Educational Research Association guidelines of ''voluntary informed consent'' (BERA 2011).

Student profile
The first section of the questionnaire aimed to gain a profile of the student population (Table 1).Thirty-seven (88%) of the respondents were aged between 18 and 21, whilst only five (12%) were aged between 25 and 34.
Of the respondents, 10 were female, and 32 were male.Laptops are the preferred device amongst respondents (50%), with 80% use by female respondents (n08) (Table 2).
Despite the market surge in demand for tablet devices, only one respondent (2.3%) uses a tablet as their primary device for Internet access.The developments in smartphone technologies are beginning to enable users (n06, 14%) to use them as primary Internet devices.

Online access
The next section in the questionnaire aimed to identify how students access the Internet, and how they spend their time online.
Chart 1 demonstrates how 48% of respondents spend between 11 and 30 hours online per week (n020), equating to between 1.5 and 4.2 hours per day.However, some students spend considerably less Á two respondents spend less than 10 hours online per week Á and some spend considerably more Á five respondents spend more than 51 hours per week online.There were also four ''other'' responses to this question, including: ''Many/Too many'' and ''Continuously''.The mean time spent online was 33 hours per week.
Chart 2 demonstrates how respondents in the 25Á34 age category are less likely to spend significant time online Á all of whom spend less than 40 hours online per week.In contrast, 13 respondents (31%) spend greater than 41 hours online per week, all of which are in the 18Á25 age category.Chart 3 demonstrates that respondents perform a range of activities online, with very few activities taking up a large percentage of overall Internet usage.In particular, no respondents spend any more than 70% of their overall time online in activities related to shopping, news and weather, or banking.In fact, these activities were those that respondents spend least time on.
Although still uneven, respondents demonstrated a more balanced distribution for activities related to social networking and study, with the majority of responses spending between 11% and 70% of their overall time online in these activities.
79% of respondents engaged in social networking (n033) between 11% and 70% of their overall time online, just as they did in activities related to study (79%, n 033).
Table 3 demonstrates that 31% (n 013) of 18Á24 year old respondents spend more than 50% of their overall time online in social networking activities, compared to just 2% (n 01) of the 25Á34 year olds.
Chart 4 demonstrates the range of practices related to study amongst respondents: . 14% of respondents spend less than 10% of overall Internet time in activities related to study. .The most common response (n 014) was between 31 and 50%. .Only three respondents spend more than 71% of their overall time in activities related to study. .36% (n08) of respondents spend over 50% of their overall time online engaging in activities related to study.
A total of 14% (n06) of respondents do not own a smartphone.Chart 6 demonstrates the range in which different people use their smartphones for access to the Internet, with a mix of answers across the boundaries.
A total of 24 respondents (57%) with smartphones use them for less than 50% of their overall Internet activity, whilst 18 (43%) use them for more than this.
Table 4 demonstrates that no respondents aged between 25 and 34 rely on their smartphones for more than 50% of their overall online activity, whilst a greater range exists amongst the lower age bracket.
Chart 7 compares smartphone users with their social networking activity.This data suggests that iPhone and Android users are more active on SNSs than users of other smartphones, and considerably more active than non-smartphone users.

Use of social networking sites
This section of the questionnaire focuses on attitudes and practices related to the use of SNSs, and in particular their use within an educational context.Respondents were asked about their prior use of SNS, their views on communication between tutors/ students, and their use of Twitter as a result of this study.A total of 79% of respondents (n 033) are active Facebook users, e.g.regularly update profiles, share photographs, participate in groups, and so on, whereas 58% of respondents are active Twitter users (n024).This could demonstrate the larger market share of Facebook amongst the student population.An additional question was included in the questionnaire for the #0002, #0004 and #0005 modules, asking respondents if they had used Facebook to discuss course related information with fellow students.One hundred per cent (n033) of existing Facebook users had used the platform to discuss course related information on an informal basis.
Table 5 identifies a mix in views related to the use of SNSs for educational activities.
There was a different view on whether Facebook or Twitter should be used in education.Whilst 29% (n012) of respondents believe Facebook should not be used, only 2% (n 01) believe Twitter should not be used.Suggesting students might perceive the role of these tools differently.
A total of 45% (n019) and 67% (n028) of respondents were positive towards the use of Facebook or Twitter in education, respectively.
Students were asked what their single preferred method of formal communication was and were given the options of Email, Twitter, Facebook or Moodle (Chart 8).Although many respondents are happy to use SNSs to communicate, Email still carries the most weight as the single preferred method for formal teacherÁstudent communication (60%, n 025), followed by Moodle and Twitter (both with 14%, n 06) and Facebook (12%, n 05).
All respondents in the 25Á34 age category preferred email to other methods.Table 6 includes responses to a free text question, asking if respondents identified benefits of using Twitter as a communication tool between teachers and students.Although the question only asked for benefits, some students included negative aspects as well.The responses have been loosely coded as below.
Fifty-eight positive comments were made relating to the use of Twitter as a communication tool, with respondents identifying the speed of communication and ease of communication as key drivers.Participating in a public forum, feelings of community, accessing links and retweets (RTs) and the informal and relaxed nature was also deemed positive.Table 7 demonstrates that a smaller number of respondents actually used Twitter to communicate with tutors (36%, n 015), with 100% of this group finding this method of contact a useful exercise.Interestingly, more respondents contacted other students (40%, n 017) rather than their tutors.
Exactly 50% of respondents (n021) had accessed a link posted by the tutor, which incidentally was greater than the amount of respondents who had communicated with the tutor via the platform.

Discussion
Only 36% of respondents (n015) communicated with tutors through Twitter; however all of those that did, found the service beneficial.Whilst this is overwhelmingly positive, there are other factors to consider before encouraging all students to use such services, such as existing digital literacies, habits, etc.
Interestingly, more students accessed links posted by the tutor (50%, n 021), than the amount of active Twitter users (36%, n 015).This would suggest the Twitter API to enable tweets to display in the VLE is a feature students have actually used and might find beneficial.It reinforces the notion that students can be inactive in the Twitter environment, but can ''lurk'' and still benefit from social influences on the Web Á a common phenomenon within communities of practice (Reed, Sherratt, and Smith 2008;Beaudoin 2002;Jansen & Zhang 2009).It further suggests that Twitter can play a key role to aid communication between teaching staff and students, as well as encouraging and supporting informal/casual learning, that is, learning outwith the formal structures of the university, between learners, and in online communities.
The researcher witnessed a significant increase in both the number of tweets and emails from students to the tutor as deadlines approached for coursework/exams.The number of tweets by students was not recorded as very few of them contained the dedicated hashtags, however the stated increase in tweets suggest that some students clearly valued Twitter over other methods in these instances.This is reinforced by the coded comments related to ''Speed'' and ''Ease'' of communication (Table 6).
The reliance upon email as the single preferred method for formal communications by the majority of respondents (60%, n 035) suggests students still value this communication mechanism.This might contradict data and views from both Pew (Lenhart et al. 2007) and Junco, Heiberger, and Loken (2011) related to decreasing email usage, or alternatively in this case, it could merely be about security Á a means for students to return to and archive important messages, as opposed to the potential for tweets to be missed on busy timelines.
As this is an isolated study, it is difficult to compare the use of email with the previous year's students, so we therefore cannot be sure if email reliance is decreasing or not.Furthermore, the small number of respondents in the ''older'' age category prevents any generalisations in relation to their reliance on email as a single preferred method of communication.

Social media and the digital divide
The data obtained in this study identifies a difference in time spent online between age groups Á all of the 25Á34 year old respondents spend less than 40 hours online per week.It also demonstrates that whilst not all students are active users of SNSs, there is no correlation between ''active SNS use'' and ''Age''.However, the data in Tables 4  and 5 demonstrates that only one of the ''older'' respondents engages with social networking to any significant degree, e.g.!50% of their overall time online, and does not rely on their smartphone for more than 50% of their overall online activity.In both questions, respondents in the lower age bracket demonstrated greater use of social networking, as well as a greater reliance on mobile technologies.
This provides an interesting insight into the digital divide.Although there appears to be a distinction between both extremely high uses of social networking and reliance on mobile devices, with ''Age'', respondents in the 25Á34 age bracket still engage online and in social networking, contradicting suggestions by Prensky, and potentially reinforcing White and Le Cornu's perspective that the Native/Immigrant classifications do not lend themselves to the Social Web, and thus require rethinking.The data therefore is in closer alignment to the idea of Digital Visitors and Residents, whereby residents see the social web as a physical place, as opposed to visitors who use the tools they need to perform a certain task (White & Le Cornu 2011).This is reinforced through the development of a community of learners, consisting of so-called Natives and Immigrants.
In recognising White and Le Cornu's notion of the Digital Visitor, we also recognise the need to support the digital literacies of students in order to harness the potential of Web 2.0 tools.This would support the view of Dabbagh and Kitsantas (2011) that students should receive suitable training in social media tools.This is particularly relevant, given that 100% of active Twitter users positively evaluated the service in relation to learning and teaching, and in particular in relation to supporting and enhancing communication.Whilst there may be differing circumstances, literacies, habits, and so on amongst the diverse student population, we can presume many other students would also have seen benefits had they been active also.Therefore, it is essential to enable all students, not just Digital Visitors, to become fluent and use the tools to enhance learning and the student experience as they see fit.Again, suitable awareness raising and support events may be required to achieve this.

Social media and PLEs
This research supports the beliefs of a number of commentators (Dabbagh & Kitsantas 2011;Hall 2009) that students are already choosing social media tools in the formation of their own PLEs; Chart 9 identifies 79% (n033) and 57% (n024) of respondents already actively using Facebook and Twitter respectively, before beginning these modules.This information suggests PLEs are owned and formed through personal choice, views and considerations, and that learners are already using these tools to support their learning in casual (or informal) settings.This is further reinforced by data identifying that 98% of active Facebook users had already used that platform to discuss university work.
This study emphasised the voluntary participation with Twitter for a number of reasons [in contrast to the enforced approach adopted in previous studies of Junco, Heiberger, and Loken (2011) and Kassens-Noor (2012)], but notably for one of personal freedom in the formation of a meaningful PLE Á if PLEs are indeed personal and assembled through personal choice, we cannot enforce specific tools or environments upon students without running the risk of disengagement.Similarly, how can such technologies be classed as informal, if they are integrated formally within curricula?Instead, learners should be shown the potential of such tools amongst a learner's repertoire or toolkit, with the hope that voluntary participation will be more likely to encourage meaningful and long-term use.Finally, the disregard of hashtags by students, whether consciously or not, could emphasise the insistence of the informal nature of the platform.

Conclusion
This exploratory study has provided a knowledge base in the underexplored area of using Twitter in education.To concur with previous authors cited, the data and discussions in this paper support the suggestion that the use of social media (and Twitter in particular) can positively impact upon various elements of teaching, learning and the student experience.In particular, this study has aligned the use of Twitter to the three Cs Á Communication, Community and Casual (informal) learning Á each of which has taken place between learners and teaching staff.With on-going challenges of learner isolation in higher education, the use of Twitter in this study might prove to be one potential solution to combat such problems.However, it is also important to recognise that Twitter is ''not for everyone''.
To further embed the positive experiences cited in earlier studies as well as those identified here, it is recommended that researchers look to archive tweets beforehand in order to sufficiently analyse social/group dynamics.Furthermore, support/training around the use of the tools is critical to get a wider uptake and to ensure students fully understand the features, e.g.hashtags.
The data gathered in this study provides some insight into the digital behaviours of students aged 25Á34, however due to the low response rate obtained it is difficult to generalise this information to anything wider than this case in particular.It does reinforce White and Le Cornu's (2011) notion of Digital Residents and Visitors, and as such prompts further research into the digital behaviours of learners, with a particular focus on age.Through such further investigation, it also raises questions related to whether age, or more specifically the level of digital literacy, should be the primary focus of investigation.
To conclude this paper, three questions have arisen through interacting with literature and the data gathered: (1) Should educational institutions take responsibility for familiarising learners with emerging technologies and embed them into learning and teaching activities?If so, how? (2) If students are already using Twitter as a personal/social tool, are there ethical issues involved in archiving and analysing their tweets/discussions?(3) If PLEs are indeed personal and these tools are informal, do we run the risk of disengaging students by formalizing them through structure?
This single case reinforces the notion that Twitter can be a useful tool to support learning and teaching, and warrants further investigation into the use of social media to enhance the overall student experience beyond the direct impact on assessment marks.As highlighted earlier, further research might consider analysing more closely the amount of tweets as well as group dynamics.However, the use of particular hashtags alone does not tell the full story, and therefore closer research into the impact of using such tools as a means to enhance communication, collaboration and casual (informal) learning is needed.
